3 ingenious examples of how design can keep us safer and healthier

One town in Iceland painted a 3D pedestrian crossing, while Lisbon installed “dancing” traffic lights, and “piano stairs” are catching on in cities all over the world.

Town in Iceland Paints 3D Zebra Crossing To Slow Down Speeding Cars

In the small fishing town of Ísafjörður, Iceland, an exciting development in road safety popped up – almost literally. A new pedestrian crossing has been painted that appears to be 3D by way of a cleverly-detailed optical illusion.

The innovative design gives pedestrians the feeling of walking on air The design also gets the attention of drivers, who will slow down their speed once they spot the seemingly floating ‘zebra stripes.’ Icelandic environmental commissioner Ralf Trylla called for its placement in Ísafjörður after seeing a similar project being carried out in New Delhi, India. With the help of street painting company Vegmálun GÍH, his vision became a reality. Source: YouTube/VegamálunGÍH
Piano Stairs: Stairs located next to escalators were transformed into a working piano The idea of the Piano Stairs struck a chord (pun intended) with people around the world, with a video of the concept clocking up over 13 million views on YouTube, with replica Piano Stairs appearing in Auckland, Melbourne, Stockholm, Milan, Istanbul and Colombia.
